# Documentation: DTS.Viewer.PSDReportSettings.Resources

## 1. Purpose

This module provides localization infrastructure for the PSD (Power Spectral Density) Report Settings UI within the DTS Viewer application. It combines a WPF XAML markup extension (`TranslateExtension`) for declarative resource binding with a strongly-typed resource accessor class (`StringResources`) that wraps a `.resx` resource file. The module enables UI elements to reference localized strings directly in XAML markup while centralizing string management for the PSD report configuration interface.

## 2. Public Interface

### `TranslateExtension` (public class)

**Namespace:** `DTS.Viewer.PSDReportSettings`  
**Base Class:** `System.Windows.Markup.MarkupExtension`  
**Attribute:** `[MarkupExtensionReturnType(typeof(string))]`

A WPF markup extension that enables XAML bindings to localized string resources.

| Member | Signature | Description |
|--------|-----------|-------------|
| Constructor | `TranslateExtension(string key)` | Initializes the extension with the resource key to look up. Stores the key in a private readonly field `_key`. |
| `ProvideValue` | `public override object ProvideValue(IServiceProvider serviceProvider)` | Returns the localized string for the provided key. Returns `NotFound` constant if key is null or empty. Returns `NotFound + " " + _key` if the resource lookup returns null. |

**Constants:**
- `private const string NotFound = "#stringnotfound#"` — Fallback string returned when a resource key cannot be resolved.

---

### `StringResources` (internal class)

**Namespace:** `DTS.Viewer.PSDReportSettings.Resources`  
**Attributes:** `[GeneratedCode]`, `[DebuggerNonUserCode]`, `[CompilerGenerated]`

A strongly-typed resource class auto-generated from a `.resx` file. Provides access to localized UI strings for PSD report settings.

| Member | Signature | Description |
|--------|-----------|-------------|
| `ResourceManager` | `internal static global::System.Resources.ResourceManager ResourceManager { get; }` | Returns the cached `ResourceManager` instance for this assembly. Lazy-initialized on first access. |
| `Culture` | `internal static global::System.Globalization.CultureInfo Culture { get; set; }` | Gets or sets the current UI culture for resource lookups. Overrides `CurrentUICulture` for this resource class. |
